1. Study examined acoustic features in voice to identify benign vocal fold lesions.
2. Key metrics: Harmonic-to-noise ratio (HNR) and pitch.
3. Included 176 participants; median age was 59.
4. Significant differences noted between benign lesions & no voice disorder.
5. HNR variability potential biomarker for lesion monitoring.
6. Challenges in differentiating lesions from other voice disorders.
7. Authors recommend larger, diverse cohorts for future research.
